Audi finally revealed today at the Paris Motor Show the well-camouflaged coupe that's been tooling around Europe. It's called the Audi Quattro, and it's a concept-only tribute to 30 years of rally racing.

Based on a massively shortened RS5, the Quattro sports a 2.5-liter five-cylinder turbo engine just like the good old days. This mill can churn 408 hp, enough to take the aluminium Quattro to 60 mph in 3.8 seconds, via the high-tech all-wheel-drive system. And the package comes close to weighing what the Sport Quattro toted in 1984.
